Need help on how to make listSFTP processor properties dynamic in NiFi ?

Explorer

Hi Folks,

My Requirement: SFTP connection setup.

Partners send files to us via SFTP. we need to fetch those files and put into respecting folder for further processing.

we are planning to use nifi technology for this sftp setup. Please help to make this happen.

We are thinking below process to implement.

First will use the ListSFTP processor for list all the files and followed by fetchSFTP processor for fetch all the files which are authorized.

Need help on, below points.

1) ListSFTP supports listing of the supplied directory (Remote Path) and supplied "Hostname" using the 'Username" and 'Password" / "Private Key Passphrase".

The password can change at a regular interval (depending on organization policy) or the Hostname or the Remote Path can change based on some other requirement.

in the above case how to set the ListSFTP properties based on the attributes.. like point 2.

( for these attributes, we are planning to prepare the csv file which will have Remorepath ,hostname, usename, and password ,and other attributes...)

2) How to read the csv file and make all make all the attributes as variables...to use in down stream flow.

3) How to route the files into target directories ( if we have sub folders based on partner..how to copy that perticular partner files into other folders.).

Thanks in Advance.

Thanks,

ListSFTP is a source processor that does not accept incoming flow files. It is made to track the state of a specific directory on a specific host and find new files, so if those values can change at anytime then the state needs to be reset. This is challenging if those values can change on any given execution while the processor is running, so for this reason the processor does not support incoming flow files and the values can only be changed by stopping and starting the processor with new configuration.
